I'm tryiing to make some more natural looking "decor" for a couple of enclosures. I'm kind of tired of the same mopani/grape vine/cork that is available at just about every pet store. I've got access to some recently cut oak, gum and pear branches.
Looking through the forum I see freezing, baking, microwaving and pesticides as options. All with various pros and cons.
For small stuff I can see the freezing, baking and/or microwaving as easy enough options. I can see that working easily enough for ground cover/mulch type decor. But what about a 3-4' branch (big enough to span a 55G aquarium)?
How would you prep something like that?
